ToWHoM rr MAY conceals: A Beit known that we, MELTIER NYE and ABRAHAM J'. KNIsE-LY, of the city of Chicago, and'Staterof Illinois,

havinvented new and useful Improvements in Brick-Machines; and we do hereby declare that the followingisa fulli, :clear, and ex'act description of the same, reference being had tothe accompanying-drwings, and to the ligures and letters of 4reference marked thereon, in svhich- Figure 1 is a. 'ront`elevat-ion.`

Figure2 is aside elevation. Figure 3 is'side view of a spring'and valve placed in front of receiving-boxU. Figurel: is a front view-of the same spring and valves. v Fignre is one view of a weight and lever to control Vthe yielding fulcru'mblock F, shown in fig-I. 2. Figure is another arrangementof-levers and Weight, shown in iig. 2. 'Figure 7 is anotherarrangementof the lever E, shown in fig. 2, and methodof governingit. f Tolenablc others skilled in-the art to makeand use o ur inventiongve willproceed to describe its construetionand operation. 4 i

The nature -and object of our 4irivention'are to construct a brick-machine, simple in its form, construction,f and o'peration,'and'to be worked by any 'powcrxdesir'eds 4 VOur machine is made of the height and breadth desired, and can be made inf circular. or square form. We.v

prefer to make it inthe square form.' It is made of framework,`and lined or sided up with plank of the requisite thickness o'n the inside, leaving the framework outside of the plank-work.

Similar letters of refer'encerefer to similar parts in the different gures. A, figs. 1 and 2,' is a shaft, passing down through the centre of the machine, andis provided with arms and afscrevv to agitate the clay and force it downwards. B is a bevelfwheel attached to the shaft A. (1 is a bevelwheel'smaller than B, attached to the shaft "a: vC is another wheel of the same s'ize as C, attached to the shaft al. D is a crank Aattached tojandl Working from the shaft a, Tprovided with a pin, D', lig, 1. E is a vibratory lever working ori-the fulcrnm E,.\v hich is attached to the'movable or `yielding fulcrum-block F. N is a lever attached at its lower end to. the'rsliaft N" at N. M is a connection, uniting lthe levers N'and E. R is a chain attachedto thel lever N, at or near its upper end passing overthesheave T, and is attached to the Weight S at its other end.; i H is a right-angled lever Working upon `its f ulcruin H located at the angle of the lever. Gris a connecting-rod, connecting the movable or yielding fnlcrnm-block F with1the short arm ofthe right-angled lever H, at the pivot G. Y is'ajveightrconnected to the long arm of the right-angled lever H by the chain I. K is an arm extending from the top of the frame of the machine. J is=a rod, extending from the end of the long arm of the right-angled'lever H, up through the extended end of theol-m7@ terminatngin a screw,and upovnwhich works the nut L. L isa rubber Washer, placed under `the nut L on therod'J. The rod J freely moves through the arm K. U is a receiving-box, locatedin front of the machine, and upon @the table Q. The table Q extends out in front of the machine, and back lunder the machine about one-half its Width. e e, iig. 1, is

a plunger, working in theA receivingbox U'. Y Zt, iig. 1, vis a'rod, connected at its lower end-l1 to the plunger e e, and at its upper end to the crank-wheel fc, attached to the shaft a.' d d arcguide-rods attached'to the plunger ee. zisa standard, fastened at therupper part ofthe front side ofthe receivingbox vj' is a spring, attached nt'one end to the upper end of the standard z', at f:. There is aseriesof.tliese standards a-nd. spring-sf, as shown in g. 1. N is a shaft passing across the machine at or near thelower end. O 0 arelevers extending from the shaft N up through the table Q. The table Q is `provided with slots for the levers 0 O to work in.l

P is a rolling-shaft extending from one lever 0 to the otherlevcr g, fig. 3, is a hinged valve, hung before the receiving-box U, at or nearits lowerl edge; these valves cover openings in the receiving-box U.` There is a series of these valves.y The valves are made nith two'ears, tt, extending` fromthenpper edge, one on each side.4 A recess is made at each-side of the valve-openings in-which they are inserted. The 'pins ii pass dow in front of these ears, and thus the valves are held in position, and admitV of' the valves working on these ears. The operation-of car invention is as follows: Porter is applied tol the shaft A in any nay desiredg'motion is thus communicated to the wheelsl C and C. The clay is forced down into the receivingbox U. The moulds to receive the elayare placed'under the machineon the table Q, in front of the rolling-shaft The clay is forced down into the moulds by the plunger e e, by means of the rod b and crankfwhoel zu.A As the crank D revolves, at each of its revolutions, the pin D comes inn contact with the upper end of the vibrator-y lever E, which working ou the fulcruin ll', the otherendmoyes in an opposite direction, causing the lever N, by'means of the connection M, to move in .the sume direction. lhis partially revolves the shaft N, and causes the levers OO, with the rolling-shaft P, to move forward, .which in turn shoves the empty moulds forward under the receiving-.box

' U, shoving the already filled mould-out from under the receiving-box U on the table Q, before which the .workman-.stands witlrstrike in hand, and vstrikes the upper surface of the bricks smooth. As, the lever N moves for- 'svard, the weight S is raised, and when the crank D relieves the lever E, the weight S brings the systemof levers back totheir proper position.

It frequently happens that stone and other obstacles will get into the machine,and*are forced ldown into the receiving-box U, and thus .forced into the moulds, and unless thereis a yielding point somewhere between the crank D and the stone or obstacle wedged in., the'mould, there would be a breakage somewhere. Thisvis .Obviated by the use of the movable fulcrum-blocliF. Whenever the moulds are arrested in passing out freni' under the receiving-bogiU, the Vfulcrum-block F will yield and allow the lever E to movebso as to allow the crankE to pass on.

By means of the right-angled'levcr H, the wcightY, vand rodJ, the movable .fulcrumF is kept at one point in the slot, in which it moves up to a certain'dgree of resistance, which is regulated byincreasing or'd'ecreasing the weight'Y; and'by adjusting the rod J by means of thenut L', the movable iu'lc'zrum-block F iskept at any point desired in the slot in which it moves.r This governing of.- the movabley fulcrum-blook F regulates the distance the rollingshaft P shoves the moulds under the receiving-box U. a V

Whenever a stone or other obstacle gets into the mould of a larger size than a brick, and thus prevents the moulds from passing out from in under the receiving-box U,'the movable fulcruurbloclc F will yield and allow `4thecrank to pass by the endot' the lever E, while the rollingbar P,iwhich shoves the moulds out from in under the receiving-box U,lremains stationary, and thus the machine sustainspno injury. As the 'fulcrum-block F moves'backward, the weightAY and rod J are raised, and when they return to their proper position, the con` cussion is relieved bylthe rubber washer L.

It frequently happens .that a. stone of a smaller size will find its way into the moulds'suiciently'large to wedge the moulds in under the receiving-bok U. Any injury' that might arise from this is obviated by the use of the hinged valves g and spring f. As the mould is shoved out, the springsfyield, and take the position of the dotted lines andthe valve takes the osition ofthe dotted lines The mould and the stone are thus ermitted p A g P to pass out, the machine in no respect sustaining any injury, or the operators loss of time. Whenever itis desired to remove the stone or obstacle before the hingedvalve g, the lower end ofthe springfis turned to one side, as shown bytl1e dotted line'sff, iig. 4, the upper ends of these springs being loosely attachedat k to admit `of this side movement. v

` The springsfpress against the valves g, withsufticient force to *enable` the vulves to resist the ordinary pressure oft-he clay. There Aare as many of these valves andspriugs as there are bricks in amould. The moulds are placed under the machine on the table Q, back of the receivingboxv U, from an opening on the left -of the machine. This opening is shown at Z, iig. l, the postet' the machine being cutaway to enable the.

moulds to pass out.

We do not confine ourselves to the specific device shown in iig. 2, for governing thc/movable fulcrum-block F. i'lhere are other methods for doingit. The right-'angled lever H can-be turned around and a weight attached to the encl,vas shown at n, fig. 5; V being the weight andthe method of applying it'. Fig. 6 Vshows anothermethod of governingT this sume fulcrum'. The lever H and its weight are dispensed with, and a'spiral spring is inserted in theA slot at one sideot` the fulcrum.

Fig. 7 shows another form of-the flever E. The lever is hinged at @just below the fulcrum E', the movable fulcrum-bloch F being 'dispensed'witlh A spring, q, is attached to the upper part of the lever'E", and extending down, works in a loop, r, attached to the lower part of the lever. The spring g is str ong enoughto worli the twoparts E and EH-of the lever E, as a whole, until some obstacle intervenes to prevent the moullsfro'mpassing out from in under the receiving-box U. When the part E becomes stationary, the partE" moves upon its hinge p, and crank l) is 'permitted 'to pass, when the spring g causes the part Em' to return to its original position; thus the machine sustains no injury. Theplunger b and the crank D move relatively.'A The' crank D passes the lever `Ejust as the plunger is in the act of rising. This relative movement is accomplished by properly adjusting the cranks x' and D.

IIn gs. i and 6, the movablefulcrum is adjusted to any desired point'iu the slot in`which it moves by means of the set-screw m.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. The combination of the movable fulcrum F, connecting-leversE, M, and N, with rolling-shaft l?, chain R, and weight S, substantially as and for the purpose shown. v

2. In combinat-il" with the .movable ful'crum F, we claim the connecting-rod G, lever H, chain I, weight y, und rod j, substantially as and for the purpose shown. i

3. Combining the adjustable Apivoted springsf with the hinged valves g, substantially as and for the purpose herein shown and described.
